The last time I got some sort of consensus was in 2000, and the list of routes was split between Trad and sport, although the sport routes in this list are all in the Cape that was because of the plethora of magnificent sports routes in every province, so we agreed that each province would have their own list of \"best sport routes\".
Trad(Adventure) routes: Jacobs Ladder (TM), Klein Winterhoek Frontal (Tulbagh), Celestial Journey (Cedarberg), Something of Value (Blouberg),
Dinkum Dog (Karbonaartjeskraal Cape). I could give you the discussion and criteria for this list, but that would bore you to death.
Sports routes (Cape only): Sterling Silver (Silvermine), Sickle Moon (The Mine), Billy the Kid (Rocklands), Gospel Express (Steeple,Montague), Wild Card (Oorlogskloof, Montague).
The arguments and updates to the above can go on forever, or else the list gets longer. It is easier to pick the best 100 than the best 10.
